Here in New York City, it can be tough to have pianos lessons a proper instrument. Many studios use inferior digital pianos or older uprights to appease neighbors. To make the best of the space and noise constraints of New York City living, we currently use a beautiful Yamaha Avant Grand N3 with true grand piano action. This way, you can experience the proper touch and sound that comes with playing a true grand piano which is necessary for proper development of finger strength and dexterity.
